KVM: arm/arm64: vgic-new: Add userland GIC CPU interface access
Using the VMCR accessors we provide access to GIC CPU interface state to userland by wiring it up to the existing userland interface. [Marc: move and make VMCR accessors static, streamline MMIO handlers] Signed-off-by: Andre Przywara <andre.przywara@arm.com> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> Reviewed-by: Christoffer Dall <christoffer.dall@linaro.org>
